BRUSH.

sPEcIFIcATIoN vforming part of Letters Patent No. 282,137, dated Julye1, 188e.

Application led March 5, 1883. (No model.)

`V .T all whom it may concern.-

Be it known that I, JOHN STAPLES WHITE,`

I do hereby declare the same to be described in the followingspecification and represented in the accompanying drawings, of whichFigure l is a side view, Fig. 2 a vertical and longitudinal section, andFig. 3 a horizontal section, of a brush provided with my invention, thenature of which is defined in the claims hereinafter presented. Thisbrush, which is intended for use in washing windows or removing dustfrom walls, 8m.,

is, as represented, ellipsoidal, .though it may be ovoidal or spherical,or substantially so, `in form. It consists of two concavo-convex blocks,A A, having `bristles B drawn into them by wires, and projecting fromtheir outer or convex surfaces, such two blocks being arranged in manneras shown, and connected by two metallic thimbles, C C', adapted to them,respectively, and joined by a screw, D, going 2 5 through the head ofone thimble .and screwed into that of the other, as represented. Each`of these thimbles may be screw-threaded in its 4interior space or bore,inorder for it to screw upon a handle or pole at one end thereof'.

Instead of having two thimbles, one may be used to extend into bothblocks, and `serve to connect or aid in connecting them together; orother proper means of connecting the blocks may be employed.

By having each block recessed or concave,

\ as well as convex, as shown, the confining wires of the bristles ofone do not interfere with those of the other, to prevent the fiat sur--face of one block coming into close contact 4o with that of the other.i

In order to prevent one block from turning out of place on the other, Iprovide them with one or more dowels,c, inserted in them; or

one block may have one or more tenons to extend from it into the other.`

With a brush consisting of two separate `brushes semi-spherical orellipsoidal inform and arranged and fastened together substantially asdescribed, there is little, if any, danger while using it of breaking awindow or injuring a surface against which it may be moved. It islespecially useful as a railwaycar-windowfcleaner. I makeno claimtoabrush composed of two semicircular blocks connected together andhavingbristles projecting from their peripheries, all being as shown inthe United States Patent No. 55,815. Nor do I claim a slatecleaner andpencil-holder composed of abottle and its stopper and sponges`encompassing 6o them, as shown in theUnited States Patent No. 221 ,883.In my brush each of the blocks is not only convex laterally, butlongitudinally, so as when supplied with bristles and placed and securedtogether 'a brush spherical, ovoidal, or ellipsoidal in form, oressentially so, is produced, which differs materially from any brush ordevice sho Wn in either of said patents.

I claimy l. A brush composed of two separate semi- 7o spherical orsemi-ellipsoidal brushes arranged and provided with one or moreconnectingthimbles, anda screw, adapted to them as represented, forconnecting them together, all being substantially as described. t

2. A brush composed of two separate semispherical or semi oval orellipsoidal brushes, arrangedand doweled or tenoned and conneotedtogether substantially as set forth.
